Securelybolted to the bars suitable strengthening or bracingbars 9 9. 23, preferably near the'platform 5, are short bars 29, betweenwhich a channel-bar 30 is pivoted. This channel-bar forms the main boomor vertically-movable arm of the hoisting mechanism and may be of anypreferred length and is preferably provided near its outer end with ashort pivoted link 31, that is pivotally connected toa bar 32, thatforms an auxiliary boom or continuation of the boom 30. The main andauxiliary booms are also preferably connected by the pivotal bar or link33. Side bars 34 are also provided, having a common pivotal connectionwith the link 3l to the boom 32 and pivoted to the bars 2S near theirturned-up ends. When the main hoisting-boom is raised to an uprightposition, as shown in Fig. 3, it enters the space between the ends ofthe bars 28 until it engages a forked stop 35, secured between theturned-up ends of the bars 28 and securely clamped to the side bars 34.At a suitable point near the outer end of the main boom 30 I provide apulley 36 and a similar pulley 37 near the lower end of the auxiliaryboom or bar 32. A suitable rope or cable 3S is attached to a bucket 39and passes over said pulleys to the sheave l5 and from thence to asuitable source of power. When the bucket is being lowered into theditch or other excavation, the main boom, with the other mechanismsconnected therewith, will drop down from its normal upright position toa position overhanging the ditch to allow the bucket to be lowered intothe excavation and filled. When the bucket is drawn up, the main boomwill be raised to the position indicated by dotted lines in Fig. l, andthe operator standing on the platform may then swing the bucket andhoisting mechanism around to the opposite side of the machine inposition for dumping.

As shown in Figs. l and 3, I prefer to cut away the flanges on theoutside at the top of the I-beam 10 to permit the main boom to be swungaround in proper position to dump the bucket. To receive the material asit is dumped from the bucket, I providea hopper 40, pivotally supportedon the arms or brackets 4l and normally locked in a horizontal positionby the spring rod orbar42. This bar is secured to the I-beam near itslower end and has a hook portion 43 near its upper end to overlap theedge of the hopper and prevent it from tilting. When, however, theoperator desires to empty the hopper of its contents, aslight pull onthe end of the springrod will disengage it from the hopper. I preferalso to provide a stop 44 to engage the edge of the hopper and preventit from tilting in toward the machine.

The hoisting apparatus may be operated by one or more horses or othersuitable power, and the mechanism for supporting the bucket being simpleand quick-acting the bucket can be raised and emptied of its contentsvery rapidly. As soon as the hopper is filled it is dumped into a wagonor car standing beneath and carried to some other point along the ditchor excavation. When the ditch or excavation has been carried down to therequired depth, the machine is moved to another point in the mannerheretofore described. The hoisting mechanism comprises but few parts, iseasy of operation, and asingle operator standing on the platform canreadily swing the bucket and hoisting mechanism around to the proper dumping position over the hopper and then dump the filled hopper into thecar or wagon beneath.

I am aware that various modifications, such as in the relativearrangements of the main and auxiliary boom and the pivotal partsconnecting and supporting the same, will suggest themselves to any oneskilled in the art, and I therefore do not wish to be confined to thedetails of the mechanism herein set forth.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with a suitable frame, of anupright partially rotating standard mounted therein, a suitable derrickdevice supported on said standard and adapted to swing therewith, saidderrick device comprising a main and an auxiliary boom, suitable bars orlinks connecting said standard and said auxiliary boom, a suitable cableand bucket carried by said derrick device, and a hopper mounted on saidframe and adapted to receive the material discharged from said bucket,substantially as described.

2. The combination, with a suitable frame, of an upright tube mountedthereon, astandard or mast pivotally supported in said frame and adaptedto describe a partial revolution around said tube, a hoisting or derrickdevice supported on said standard and adapted to swing therewith,suitable sheaves provided on said standard and derrick device, and arope or cable passing over said sheaves and through said .tube to asuitable source of power, substantially as described.

3. The combination, with a suitable frame, of a fixed upright standardmounted thereon, a partially-rotatable standard supported on said fixedstandard, a boom pivotally connected with said rotatable standard, anauxiliary boom, suitable bars or links pivotally connecting said mainand said auxiliary booms, side bars or links pivotally connecting saidauxiliary boom and said rotatable standard, suitable sheaves or pulleysprovided on said standards and said booms, a hoistingbucket and asuitable cable passing therefrom oversaid pulleys to a suitable sourceof power, substantially as described.

4. In a machine of the class described, the combination, with a fixedupright tube, of a stud provided beneath the same, a sheavecasingrevolubly supported between said tube and said stud, a sheave mountedthereon, a suitable hoisting mechanism supported on said tube, and arope or cable passing over said sheave through said tube to a suitablehoisting-bucket, substantially as described.
